FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats.

I. IMPORTANT CHANGES - As announced earlier, the 2.7.x series now uses the new subpixel hinting mode as the default, emulating a modern version of ClearType.
This change inevitably leads to different rendering results, and you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option to adapt it to your taste (or use the new `FREETYPE_PROPERTIES' environment variable). See the corresponding entry below for version 2.6.4, which gives more information.
- A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been introduced. If set (which is the default), an environment variable `FREETYPE_PROPERTIES' can be used to control driver properties. This allows to select, say, the subpixel hinting mode at runtime for a given application. See file `ftoption.h' for more.
II. IMPORTANT BUG FIXES
- After loading a named instance of a GX variation font, the `face_index' value in the returned `FT_Face' structure now correctly holds the named instance index in the upper 16bits as documented.
- A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face is a named instance.
- More fixes to GX font handling.
- Apple's `GETVARIATION' bytecode operator (needed for GX variation font support) has been implemented.
- Another round of fuzzer fixes, mainly to reject invalid fonts faster.
- Handling of raw CID fonts was broken (bug introduced in version 2.6.4).
- The smooth rasterizer has been streamlined to make it faster by approx. 20 .
- The `ftgrid' demo program now understands command line option `-d' to give start-up design coordinates.
- The `ftdump' demo program has a new command line option `-p' to dump TrueType bytecode instructions.
